Winter wheat yield forecasting in Ukraine based on Earth observation, meteorological data and biophysical models

► NDVI-based model can be used to predict winter wheat in Ukraine two to three months prior to harvest. ► Performance of models varies within agro-climatic zones. ► Models were robust while adding new NDVI and winter wheat yield data. ► NDVI-based models gave similar accuracy to meteorological and CGMS models while providing minimum requirements to input datasets.
